A historian of alchemy who teaches at Yale University. Her alma maters include Bates College and New College, Oxford. She prefers tea to coffee, and her favorite food is pizza. When she’s not in the library, she might be found on the river in a quite long, very narrow boat. Daughter of Rebecca and Stephen, and wife of Matthew Clairmont. She also happens to be a witch, and a weaver.

Also known as Matthew de Clermont and Matthew Roydon, Matthew is the son of Ysabeau de Clermont and husband of Diana Bishop. He is a geneticist, vampire, and fellow of All Souls College at Oxford University. His educational credentials are too extensive to list here. In addition to working in his laboratory, Matthew enjoys reading books written by old friends and collecting wine.

An English aristocrat and Matthew’s friend in 1590-1591, Henry Percy is not yet known as ‘the Wizard Earl’ when Diana meets him. Percy is a man with a formidable education, an impeccable lineage, and a generous heart.

An English mathematician and Matthew’s friend in 1590-1591, he’s a member of that group of radicals and free-thinkers, the School of Night. Like Marlowe, he is a daemon. But instead of imagining daring deeds and lost loves, Harriot is interested in mysteries of nature–especially those found in mathematics and the stars.
